THRESHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 782,363, dated February14, 1905.

Application filed January 20, 1903. Renewed December 10, 1904- SerialNo. 236,393.

To all whmn it may concern:

I Be it known that I, JosErH H. SoMMER, a citizen of the United States,residing at Dayton, in the county of Dickinson and State of Kansas, haveinvented certain new and useful Improvements in Threshing-Machines; andI do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same. This invention relates to improvements ingrain-separators for band-cutters, self-feeders, or the like.

The object of the invention is to provide a combined cutter andseparator adjacent to the threshing-cylinder and a specific arrangementof means coacting with the cutting mechanism and the said cylinder toefiectively and thoroughly thresh the grain. a

I propose to position a shaft in the elevator and mount thereon a seriesof concave disks bearing knives at their peripheries at determinedintervals. The disks are beveled at their peripheries to an edge, whichpenetrates and separates the bundles of grain, while the knives severthe ties. Then when the grain passes from the separating-disks it isdelivered to the'top of the threshing-cylinder; but instead of passingdirectly between the heaters or knives of the cylinder and like knivesof the concave I extend the concave and pivot opposite there'- to a shoeto control the grain delivered to the threshing-cylinder. Moreover,lateral breaking-bars are placed between the extension and the cylinderto break the grain before the knives of the concave are reached.

The construction and arrangement of the parts will be more fullydescribed, and particularly pointed out in the claims.

In the drawings forming a part of this speciiication, Figure 1 is asectional view of my improvement as applied to a thresher. Fig. 2 is anenlarged detail top plan view of the combined cutter and separator. Fig.3 is a detail perspective view of the threshing-concave and itsextension. Fig. 4 is a detail elevation of one of the disks and itsknives; Fig. 5 is a detail view showing the open position of theregulating-shoe. Fig. 6 is a broken perspective showing the means foradjusting the position of the feed-regulating shoe.

The same numerals refer to like parts in all the figures.

1 represents a thresher of ordinary construction; 2, thethreshing-cylinder; 3, the concave therefor, and 4 the elevator.

At or near the upper end of the elevator 4 and in proximity therewith isa shaft 5, suitably revolved, on which are mounted two sets of concavedisks 6'and 7, the sets being oppositely disposed from the center. Thedisks 8 of the sets are mounted to rotate with the shaft and are spacedfrom each other by spacing-blocks 9. The inner disks of the two sets arenot spaced, so that at the center of the bundle of grain being carriedby the elevator the greatest resistance may be applied to out the bandsto insure the grain being spread out before the threshing-cylinder isencountered.

10 indicates a series of knives fastened near the outer edge of thedisks and projecting outwardly therefrom, as clearly shown in Fig. 4.

The concave 3 is extended up to substantially the top of the ,cylinder2, at which point it is arranged vertically at 11, and, if desired,

this vertical portion may be made adjustable toward the elevator 4:. Ashoe 12 is hinged opposite the top of the extension and is ad apted tobe locked in any fixed position with relation to the cylinder by theoperation of a hand-lever 14:, fixed to the shoe and cooperating withthe usual dog and notched segment 1A. The function of the shoe is toregulate the grain coming from the elevator to the cylinder. If the shoeis located in the position shown in Fig. 1, obviously the space betweenit and the cylinder will be of such proportions that but a limitedsupply of grain will pass into the space 15. This is primarily used whenthe grain is damp, and if when in this condition it be permitted to passfreely into the space it would soon choke the machine. When feeding drygrain, the shoe is thrown up against the vertical portion 11 of theextension, as shown in Fig. 5. Hence the opening to the space 15 islarge enough to permit the free and unlimited supply of grain comingfrom the elevator to enter. A pair of parallel beating-bars 16 extendacross the extension and project into the space 15, and below these barsare the usual knives or breakers, which coact with like knives on thethreshing-cylinder.

In operation the bundles of grain are placed on the elevator 4, and whenthey contact with the disks the knives thereon sever the ties, whereuponthe disks segregate the straw and spread it on the elevator, so that bythe time the upper end of the elevator is reached the straw fallsuniformly to the top of the threshercylinder. The grain in being spreadout toward both sides of the elevator is so loosened that the knivespass freely between the particles thereof and prevents them cutting thestraw into short sections.

I place great stress on the relative position of the threshing-cylinder,the shoe, and the elevator in that by delivering the grain to the top ofthe cylinder the quantity of grain introduced to the space 15 may beconveniently and inexpensively controlled.

What I claim as new is 1. In a thresher, the combination with aconveyer,a rotary shaft, a series of concave disks mounted on the rotary shaftarranged near the delivery end of said conveyer, the central disks ofthe series being parallel and abutting and knives projecting from theedges of the disks.

2. In a thresher, the combination with a conveyer, a rotary shaft,concave disks mounted on the rotary shaft and arranged near the deliveryend of the conveyer, said disks being arranged in two series, the disksof one series being parallel with the disks of the other and thecontiguous disks of the two series abutting, and knives projecting fromthe edges of the disks.

3. In a thresher, the combination with a conveyer, concave disks mountedon a rotatable shaft near the driving end of the conveyer, knivescarried by each of the disks, a 45 threshing-cylinder, a concavetherefor, the upper end of which extends toward the conveyer, and a shoehinged opposite the extended portion of the concave, and means connectedwith said shoe and operative from 5 outside the conveyer to alter theinclination of said shoe, whereby to regulate the grainsupply to thecylinder, as and for the purpose described.

In testimony whereof I have aflixed my sig- 55 nature in presence of twowitnesses.
